The invention discloses a system and method for releasing travel time by being accurate to a second. A plurality of video tracking units are continuously arranged on a road where the travel time is required to be released by being accurate to the second, vehicles are continuously tracked through the video tracking units, the travel time of each vehicle in the video tracking range of each video tracking unit can be obtained through a travel time acquiring module of each video tracking unit, and therefore any facility does not to be arranged on the vehicles, and the fact that the travel time is released by being accurate to the second can be achieved and is easier to achieve. In addition, the travel time given by the travel time acquiring modules is accurate to 10 milliseconds, and therefore the fact that the error of the result of the travel time acquired by each video tracking unit can be controlled within positive and negative 10 milliseconds can be guaranteed. Therefore, the accumulative ...
